[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] According to the appendix Figs. 1 to 6The filling and quantifying mechanism of the bean grinder pressure coffee machine comprises a rack, a powder grinding assembly 1, a powder pressing assembly and a hopper assembly 2 installed on the rack, the hopper assembly 2 is adapted to be screwed on the powder grinding assembly 1, and the powder grinding assembly 1 is communicated with a powder outlet channel 11 for inputting coffee powder into the hopper assembly 2. The powder grinding assembly 1 is provided with a powder grinding micro switch assembly 3 for controlling the powder grinding action or stop, the powder pressing assembly comprises a powder pressing stirring head 4, a powder pressing driving motor 5, a transmission component 6 and a quantifying control component 7. The output shaft of the powder pressing driving motor 5 is connected with the input end of the transmission component 6, the output end of the transmission component 6 is connected with a transmission shaft 8 which can move up and down on the hopper assembly 2 under the pushing of the coffee powder accumulation in the hopper assembly 2 or the gravity of the transmission shaft 8.

[0023] The powder pressing stirring head 4, the powder pressing driving motor 5, the transmission component 6 and the quantifying control component 7 of the powder pressing assembly are matched to make the powder pressing stirring head 4 located in the hopper assembly 2, and the powder pressing stirring head 4 is driven by the powder pressing driving motor 5 and the transmission shaft 8, and the powder pressing stirring head 4 compacts and flattens the coffee powder in the hopper assembly 2. During the process, the coffee powder continuously increases to push the position of the powder pressing stirring head 4 in the hopper assembly 2. When the powder pressing stirring head 4 is pushed to the set position, the transmission shaft 8 touches the quantifying control component 7, and the quantifying control component 7 is opened, so as to control the powder grinding assembly 1 to stop working. The structure is simple, the coffee powder amount can be accurately quantified, the compaction degree of the coffee powder and the coffee powder amount can be avoided from having large errors, and the coffee flavor can be ensured.

[0024] Referring to Figs. 1 to 6 Further refinement is shown in the figure, the quantifying control component 7 is distributed on the left side of the transmission shaft 8, or the right side of the transmission shaft 8, or both sides of the transmission shaft 8.

[0025] The figure shows that the quantifying control component 7 is distributed on both sides of the transmission shaft 8, so that the quantifying control component 7 is electrically connected with the powder grinding assembly 1 in parallel conduction mode, and the control accuracy is increased.

[0026] Referring to Figs. 1 to 6 Further refinement is shown in the figure, the transmission shaft 8 is provided with a spring driving piece 9 for pushing the quantifying control component 7 to move to both sides with the up and down movement, and the spring driving piece 9 is installed on the outer edge of the transmission shaft 8 and is in sliding connection with the quantifying control component 7.

[0027] The quantitative control component 7 includes a contact piece mounting member 71, a contact piece return spring 72, a contact piece spring 73, and a contact piece terminal 74. The contact piece terminal 74 is fixed to the contact piece mounting member 71, and the contact piece mounting member 71 is connected to the spring driving member 9 and moves up and down with the transmission shaft 8, and can move left and right on the fixed part of the transmission component 6. The two elastic ends of the contact piece return spring 72 are connected to the fixed part of the transmission component 6 and the contact piece mounting member 71, respectively. The contact piece spring 73 is installed on the contact piece mounting member 71 and moves with the contact piece mounting member 71 to communicate or disconnect with the contact piece terminal 74, so as to control the contact piece terminal 74 to be connected or disconnected with the grinding micro switch assembly 3.

[0028] In actual operation, the transmission component 6 is provided with a contact piece pressing plate 75 for limiting the movement position of the contact piece mounting member 71. The transmission component 6 is provided with a pivot return spring 10 for assisting the return movement of the transmission shaft 8. One side of the contact piece pressing plate 75 is connected to the elastic end of the contact piece return spring 72.

[0029] In addition, the transmission component 6 includes a transmission gear set 61 and a transmission gear box 62. The grinding assembly 1 is provided with a grinding support 12 matched with the transmission gear box 62. The transmission gear set 61 is installed in the transmission gear box 62, and the input end and the output end thereof are connected to the output shaft of the compression powder driving motor 5 and the transmission shaft 8, respectively. The transmission gear box 62 is fixedly installed with the contact piece terminal 74 and slidably connected with the contact piece mounting member 71.

[0030] Parameter Figs. 1 to 3 As shown, the grinding micro switch assembly 3 is further refined, and is installed on the grinding assembly 1 through the grinding support 12. The funnel assembly 2 is screwed on the grinding support 12 and triggers the grinding micro switch assembly 3, so that the grinding micro switch assembly 3 is actuated.

[0031] The grinding micro switch assembly 3 includes a micro switch 31, a push rod 32, and a switch return spring 33. The micro switch 31 is installed on the grinding support 12 and is electrically connected to the grinding assembly 1 and the compression powder driving motor 5. The push rod 32 is connected to the grinding support 12 and moves up and down. The switch return spring 33 is sleeved on the upper end of the push rod 32, and the two elastic ends of the switch return spring 33 are connected to the grinding support 12 and the push rod 32, respectively. When the funnel assembly 2 is screwed on or off the grinding support 12, the push rod 32 is pushed to move up or down under the elastic action of the switch return spring 33, so that the push rod 32 triggers the micro switch 31 to be connected or disconnected.

[0032] When in use, the hopper assembly 2 is screwed on the grinding support 12, and the hopper assembly 2 is in contact with the push rod 32 and lifts the push rod 32, so that the micro switch 31 is actuated to be closed, and the grinding assembly 1 starts to grind the coffee beans.

During this period, the powder pressing driving motor 5 is actuated, and the transmission gear set 61 of the transmission component 6 cooperates with the structure of the transmission shaft 8 to drive the powder pressing stirring head 4 to rotate, and the coffee powder in the hopper assembly 2 is flattened and compacted by the rotating powder pressing stirring head 4.

[0033] With the increase of the coffee powder, the powder pressing stirring head 4 is pushed up. At the same time, the transmission shaft 8 drives the spring driving component 9 to move upward. The inclined surface of the spring driving component 9 is in contact with the contact piece mounting member 71, and the contact piece mounting member 71 is moved to the two sides along the transmission gear box 62, so that the two contact spring pieces 73 are separated from the contact piece terminal 74, the circuit is disconnected, and the grinding micro switch assembly 3 is controlled to be disconnected. In this way, a signal can be generated to the control system of the coffee machine to stop or delay the work of the grinding assembly 1 for a certain period of time. This structure is simple, low in cost and high in reliability. Since the contact spring piece 73 can be separated from the contact piece terminal after the transmission shaft 8 rises to the same height each time, the amount of powder under the powder pressing stirring head 4 is certain, so that the quantitative grinding and powder pressing are realized, the compaction degree of the coffee powder and the amount of the coffee powder are prevented from having large errors, and the flavor of the brewed coffee is ensured.

[0034] When the grinding and powder pressing are completed, the hopper assembly 2 is screwed off, and under the action of the gravity and the rotating shaft reset spring 10, the powder pressing stirring head 4 and the spring driving component 9 move downward with the transmission shaft 8, and then under the action of the contact piece reset spring 72, the two contact piece mounting members 71 move to reset, so that the contact spring piece 73 is in communication with the contact piece terminal 74, and a communication signal is generated to the control system to enter the standby state.

[0035] During this period, the quantitative control component 7 and the grinding micro switch assembly 3 with this structure can simplify the structure arrangement and ensure the product structure arrangement.
